What is the best month to travel from Chongqing to the three northeastern provinces?

Heilongjiang: July is the best, and Harbin Sun Island is more beautiful; Jingbo Lake in Mudanjiang is more charming;

Jilin: If you go to Changbai Mountain, the best time is from July to September, otherwise Tianchi will freeze;

Liaoning: Benxi Water Cave is worth a visit. Qianshan, not bad; If you go to Dalian, May ~ 10 is ok, but May or 10 is the best, neither too hot nor too cold, and the temperature is very suitable.

Traveling with a group is not easy, especially for a girl. Have a nice trip.
